of colouration and in the form of the copulatory foot. Thus in Gl. 

 pallida the testaceous band on the tergites is wider; the lateral por- 

 tions of the first tergite are exceedingly widely testaceous, the black 

 not touching the striate portion as it does in this new species; the 

 antennae, too, in pallida are fuscous and not white as in albicornis; 

 and moreover in pallida the posterior process of the third segment 

 (figured and described as the fourth) of the copulatory foot is longer, 

 pointed and more or less blade-like, instead of being short and obtuse 

 as in albicornis. 



25. Glomeris infuscatus, sp. n. PI. XIX, fig. 10 — 10 b . 

 Sumatra: Mount Singalang, several specimens. 



Colour. — The upper surface a dark slate grey , the extreme edges of 

 the tergites paler; in the posterior half of the body there is a feebly 

 marked pale spot in the middle of the hinder edge of the tergites; ventral 

 surface pale; legs lightly infuscate. 



Eyes composed of seven ocelli; six in a longitudinal series and one 

 external to this series. 



Nuchal plate (l»t tergite) marked by two conspicuous arched grooves 

 which cross it from corner to corner. 



Second dorsal plate marked laterally with from nine to twelve striae , 

 most of which cross the summit of the plate ; the rest of the ter- 

 gites marked laterally and inferiorly with two or three striae. 

 All the tergites smooth but marked with exceedingly small, close-set 

 punctures. 



Anal tergite in the female convex from side to side, nearly straight 

 from above downwards; in the male, with the hinder border emar- 

 ginate in the middle and with a conspicuous depression just above the 

 emargination. 



In the male the 17 th pair of legs are exceedingly short, the 18 th 

 are much longer than the 17 th but shorter than the 19 th or copulatory 

 pair; the coxal lamina is long and piriform, projecting as far as the 

 distal margin of the second segment of the copulatory feet, with a 

 short and slender process on each side; the first segment of the 

 copulatory feet is long and bears no process, the second is produced 

 posteriorly into a digitiform prolongation , the apex of which extends 

 as far as the apex of a similar but much smaller digitiform prolong- 

 ation from the third segment, which is somewhat compressed; the
